This proposal supports the continuation of the JGOFS core measurement component of the Hawaii Ocean Time series (HOT) program for an additional three years. This HOT JGOFS proposal includes 4 separate, but fully integrated proposals: core measurement component (D. Karl, L. Tupas and D. Hebel, co P.I.s), pigment and phytoplankton component (R. Bidigare, P.I.), inorganic carbon (C.' Winn, P.I.) and zooplankton (M. Landry, P.I.). Since Oct 1988, a comprehensive suite of ocean measurements and results of in situ experiments have been obtained at the oligotrophic Station ALOHA (22'45N, 158'00'W) in the subtropical North Pacific Ocean. The core measurements were selected to provide a data set to validate existing C-N P biogeochemical models and, if necessary, to improve them. Foremost in importance among the various ecosystem processes under investigation are: the flux of carbon at the air sea interface, the rates and control mechanisms of primary production and particle export, and the pathways and intensities of inorganic nutrient (N and P) fluxes. Equally important are the observed time dependent changes in microbial biomass and biodiversity, and the relationships of these observed ecosystem changes to the broader extratropical climate forcing such as El Nino Southern Oscillation (ENSO) and other large scale ocean atmosphere interactions. The emergent data set from the HOT program is unique, robust and rich with previously undocumented phenomena. The HOT program data base is fully accessible with unrestricted use by anyone through the worldwide Internet system (ftp) and, more recently, via the world wide web with only an approximately 6 12 month processing delay. The scientific results of the HOT research program have provided an unprecedented view of biogeochemical cycles in a previously undersampled region of the world ocean. Numerous HOT related publications and reports have already appeared based on the research results obtained by a broad spectrum of HOT program associated and independent scientists. At the same time, this ocean research program has provided an unique educational opportunity for undergraduate and graduate students from Hawaii and around the world, both in terms of at sea field experience and in the classroom working with the computer accessible HOT program environmental data sets. Funding will be used to continue this successful ocean time series core measurement program for the period Aug 1998 to July 2001 and supplement these measurements with an additional mooring.

该建议支持夏威夷海洋时间序列（HOT）计划的JGOFS核心测量部分的继续进行三年。该热JGOFS建议包括4个单独但完全集成的建议：核心测量成分（D. Karl，L。Tupas和D. Hebel，Co P.I.S），颜料和植物浮游生物组件（R. Bidigigare，P.I。），无机碳（C. C. C. 'Winn，P.I。）和Zooplankton（M. Landry，P.I。）。自1988年10月以来，在北太平洋亚热带的寡头营养站Aloha（22'45n，158'00'w）中获得了一套全面的海洋测量和原位实验结果。选择核心测量值以提供数据集，以验证现有的C-N P生物地球化学模型，并在必要时进行改进。在调查的各种生态系统过程中，重要性最重要的是：空气界面处的碳的通量，一级生产和颗粒出口的速率和控制机制，以及无机养分（N和P）通量的途径和强度。同样重要的是观察到的微生物生物量和生物多样性的时间依赖性变化，以及这些观察到的生态系统与更广泛的遍地气候强迫（例如El Nino Southern振荡（ENSO）和其他大型海洋大气相互作用）的关系。 HOT程序中的新兴数据集具有独特，强大的和丰富的现象。通过全球互联网系统（FTP），任何人无限制地使用热门程序数据库，并且最近通过万维网，只有大约6个12个月的处理延迟。热门研究计划的科学结果为世界海洋先前采样区域中的生物地球化学周期提供了前所未有的观点。基于广泛的热门计划和独立科学家获得的研究结果，已经出现了许多热门相关的出版物和报告。同时，这项海洋研究计划为来自夏威夷和世界各地的本科生和研究生提供了独特的教育机会，无论是在海上田野体验而言，都在与计算机可访问的热门计划环境数据集的课堂上。资金将用于继续在1998年8月至2001年7月的这一时期成功的Ocean Time Series核心测量计划，并以额外的系列补充这些测量值。
